The 'Rainbow People' who meet around the world for meditations and NAKED gatherings where they 'express their love for each other'
全世界的彩虹聚会!男女裸身沉思,坦身相对,表达爱意

This kind of behaviour has been going on for years! I remember reading a history book in Amsterdam about a religious sect who believed it was necessary to be totally nude in public in order to commune properly with god. And that was in the 17th century! And over in England around the time of the English civil war, a sect of people believed in free love and nudity to attain a connection with god. No doubt if one did more research you may find public nudity etc, going much further back in time, perhaps?
